6 Superfoods for Arthritis

Bonus: Eating fatty fish might help people with autoimmune forms of arthritis, including rheumatoid arthritis, better manage their condition. The American Heart Association also recommends eating fish twice a week to protect your heart.

Not a fish fan? Consider taking a fish oil or algae-based supplement that contains EPA and DHA.

Superfood No. 2. Olive oil

Extra-virgin olive oil doesn't have many omega-3s, but it does contain other unsaturated fats that similarly help quiet inflammation in the body, says Prest. This flavorful oil might even help slow the deterioration of cartilage in people with osteoarthritis, according to a research review published in Nutrients.

Perhaps most exciting for arthritis patients, however, is the fact that olive oil contains a compound called oleocanthal. Scientists have determined that oleocanthal has a mechanism of action that's similar to the way NSAIDs like ibuprofen and naproxen work to ease pain.

While no one is suggesting that you can toss your pills if you indulge in spaghetti aglio e olio (spaghetti with garlic and oil) more often, swapping saturated fats like butter for olive oil should help decrease inflammation throughout your body and might make your osteoarthritis more tolerable. (Plus, it's better for your heart.)

Superfood No. 3. Cherries

The ruby red hue is a hint that sweet cherries are packed with anthocyanins, potent antioxidants that are also found in blueberries and raspberries. Anthocyanins “may help minimize oxidation and oxidative stress that contribute to inflammation,” including in your joints, says Amidor.

Some research also suggests that cherry consumption might decrease levels of C-reactive protein, an inflammatory protein that's associated with autoimmune forms of arthritis (like rheumatoid arthritis), as well as OA.

Superfood No. 4. Garlic

This pungent vegetable in the allium family is often touted for its ability to help ward off cancer, heart disease and the common cold. There’s also reason to believe that it might reduce the risk of osteoarthritis. Several studies have suggested that loading up on garlic might translate to less pain from osteoarthritis of the hip or knee, according to a 2022 research review published in the European Journal of Pain.

Scientists think anti-inflammatory compounds in garlic interfere with prostaglandins, hormones that are produced at the site of damage or infection. Components in garlic may also combat inflammatory cytokines (proteins) that might otherwise damage cartilage.

Superfood No. 5. Spinach and kale

These leafy greens are loaded with vitamin K, which research suggests is important for cartilage health, says Prest. That might explain why observational studies have found that older adults who don't get enough K, which also plays a role in strengthening bones and helping blood to clot, are more apt to develop OA. Some scientists believe that vitamin K helps with arthritis by preventing the cartilage from calcifying (hardening).

While adding more spinach and kale to your diet will also give you a boost of folate, vitamin C, vitamin A and calcium, don't rapidly up your intake if you take a blood-thinning drug like warfarin (Coumadin). The vitamin K in these greens can counteract the impact of your blood thinner, so be sure to check with your doctor before making any major dietary changes.

Superfood No. 6: Honey ​

There’s been some buzz around honey’s purported health benefits since ancient times, and while more research is needed to see whether they truly hold up, this sticky substance contains numerous natural compounds that explain how it might help people with osteoarthritis. According to a 2021 report published in Frontiers in Pharmacology, these include flavonoids (plant-based antioxidants) such as quercetin and apigenin, which counter inflammation. What’s more, some honey-derived flavonoids, including luteolin, have been found to inhibit matrix metalloproteinases, enzymes that play a role in degrading joint cartilage.
